چکیده

Final remarks Pollinator-limitation and resource constraints results in only a small proportion of an orchid population giving rise to the subsequent generation. This is further limited, as most orchid populations, particularly in the tropics, are small, due to the fluid nature of the niches they occupy and the availability of mycorrhiza ‘islands’. This combined with low reproductive success results in a small effective population size (Ne), followed by genetic drift as the potential initial cause of evolution. Subsequent diversification and speciation occurs through Darwinian adaptation to the local pollinator population. While much still remains to be learnt within orchid biology, there is now a mass of literature on their pollination biology and phylogenetic relationship. However, much of this has been the description of patterns; what is now needed are studies into the processes that drive diversification in this most remarkable of flowering plant families.
